Dynamically Making Fields Mandatory Based on Conditions

Introduction: – 

In Oracle APEX, making fields dynamically mandatory based on conditions enhances form usability and ensures data accuracy. This functionality allows fields to become required or optional depending on user inputs or specific business rules. By leveraging dynamic actions and conditional logic, developers can create responsive and user-friendly applications. This approach reduces errors and improves the overall user experience.

The following technologies has been used to achieve the same.

• Oracle APEX
• Java Script

Why we need to do: –  

Improve Data Accuracy: Ensures mandatory fields are filled based on specific conditions, reducing incomplete or invalid submissions.

Enhance User Experience: Simplifies forms by showing required fields only when relevant, avoiding unnecessary complexity.

Streamline Workflows: Adapts to dynamic business rules, making forms responsive to user actions. Reduce Errors: Prevents submission of incomplete data by enforcing mandatory fields conditionally.

How do we solve: –

STEP 1: Add the required page items.

STEP 2: Create a dynamic action with a “Change” event. For example, create a dynamic action on the “Experience” field. if the experience is greater than 1 year, both the “Commission” and “Project Name” fields are made mandatory.

STEP 3: Add below java script code True Action.

const requiredFields=[‘P7_COMMISSION’,’P7_PROJECT_NAME’];
if ($v(‘P7_EXPERIENCE’)>1){
requiredFields.forEach(field=>{
$(‘#’+field).attr(‘required’,true);
$(‘#’+field).attr(‘placeholder’,’Required’);
});
}
else{
requiredFields.forEach(field=>{
$(‘#’+field).removeAttr(‘required’);
$(‘#’+field).removeAttr(‘placeholder’);
});
}

Conclusion: –

In conclusion, implementing dynamically mandatory fields in Oracle APEX is a powerful way to improve form interactivity and ensure data accuracy. By using dynamic actions and conditional logic, developers can tailor the user experience to respond to real-time inputs, making the application more intuitive and error resistant. This approach not only enhances the usability of forms but also ensures that users provide the necessary information in alignment with business rules, leading to a more efficient and seamless experience.

Output: –
If experience is 1 then commission and project name fields are not mandatory.

If experience is greater than 1 then commission and project name fields are mandatory.
